The G-force thingy is pretty much impossoble to make i would expect and the track position one maybe too, though you could possibly update the default one from the game
For G-Force square we need a new version of GPxPatch. SDI once was working on this but I assume he stopped his activity for GP4 - unfortunately because GPxPatch is one of THE basic tool
theres another little tweak too, minor as it is. if you notice on the tv it shows the first initial of the drivers first name for each driver now (ex - F Alonso, K Raikkonen..etc). In the game, it only does this if drivers share a common surname.
